Receiver macro modeling including DC, filter, and preamplifier nonlinear properties for packaging system transient simulations

Abstract

A receiver macro modeling method is proposed. It includes the Mpilog macro model and the filter-preamplifier model which consists of small signal model followed by the hyperbolic-tangent function nonlinear post-processing. By using the directional junction model, we make use of the Mpilog model for receiver input port DC and nonlinear reflection properties, and make use of the small-signal/hyperbolic-tangent model for the output port of the preamplifier. Each model works at its own condition without unwanted interfering to each other. The assembled receiver macro model can be used in packaging system transient simulations directly. A practical modeling procedure in detail is described in the paper. The comparison between the proposed model and the original transistor-level model are given to evaluate the accuracy and simulation speed. Several application examples are also shown as test cases including high-end server packaging system transient simulations taking into account the crosstalk from the adjacent aggressor channels.
